Clay Wikipedia

Clay is a type of fine-grained natural soil material that contains hydrous aluminium phyllosilicates (clay minerals) that develops plasticity when wet. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to particle size and geometry as well as water content, and become

Clay mineral Chemical and physical properties Britannica

Clay mineral Clay mineral Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure.

Shale an overview ScienceDirect Topics

Clay content varies from 15% to > 90%; the high surface area of phyllosilicates, combined with surface charge distribution, gives rise to mechanical and geochemical properties that lead to swelling or shrinking, slaking, softening and weakening. Chemo-mechanical coupling is of great importance, in contrast to other rock types.

Kaolin an overview ScienceDirect Topics

Kaolin is the most important clay material to improve surface smoothness for better print quality. Clay materials are natural, earthy, fine-grained, and plate-like materials, and the terms clay and kaolin are used interchangeably. Chemically, clays are hydrous aluminum silicates with an approximate composition of Al 2 O 3 –2SiO 2 –2H 2 O

Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Quartz is also very hard, and doesn’t have cleavage, so it is resistant to mechanical erosion. As weathering proceeds, the ferromagnesian silicates and feldspar are very likely to be broken into small pieces and converted into clay minerals and dissolved ions (e.g., Ca 2+, Na +, K +, Fe 2+, Mg 2+, and H 4 SiO 4).

The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins.
